LIQUID MIXING .AND SPRAYING DEVICE.

Application led July. 12, 1922. Serial No.. 574,572.

My invention relates to mixing and washing apparatus for use 'in washing articles with a liquid, or a liquid solution, and the objectl'of my invention is to provide an improved device or apparatus of this kind.

It is also an object of thisinvention to provide a simple, efficient and inexpensive apparatus of this class adapted to be attached to a water supplying faucet and to be used l0 in washing dlshes and the like.

My improved washing apparatus in its best form, is constructed with a vessel for holding soap or the like associated with a four-way cock whose valve chamber is provided with a main inlet port connected with one end of a flexible hose adapted at its opposite end to be separably connected with a water supply or the like, for example with the faucet of a water system; a mam outlet port connected with a manually manipulated flexible delivery hose, and two by-pass ports communicating with the interior of said vessel. Within the valve chamber is arranged a valve controlling all of the ports and constructed so that when placed 1n one position the by-pass ports that communicate with the interior of the vessel are closed and unrestricted communication is established between the other two ports; when placed in a second position the two by-pass ports communicating with the interior of the vessel are connected, one with the main inlet port and the other with the main outlet port, while at the same time restricted communication is established between the two main ports, and when placed in a third position said valve stops altogether the flow of liquid through the apparatus. Thus when the valve is placed in the first position clear water only will be., discharged from the delivery hose; when placed in the second position a portion of the stream passing through the apparatus will be diverted through the soap holding vessel so that soapy 45 water will be discharged from the delivery Figure 1 is an elevation of a mixing and washing apparatus constructed in accordance with m invention showing the same applied to a ot Water faucet.

Figure 2 is a section on line 2 2 of Fig. 1.

Figure 3 is a sectional view of the soap holding vessel of the apparatus.

Figure 4 is a side elevation, partly .insection, of the lower portion of the soap holdmgwessel.

4igure 5 is an elevation of the valve of the four-way cock.

Figures 6 and 7 are sectional details showing diHerent positions of the'valve of the four-way coc Having reference to the drawings, 1 represents the body of a substantially cylindrical metal vessel formed at its upper and lower ends with threaded apertures 2 and 3, respectively, the upper opening 2 being normally' closed by a removable threaded cap 4 screwed therein. A gasket 5 of leather or the like may be lpositioned between the cap 4 and the body 1 as shown in Fig. 3 to seal the joint between said parts. Into the lower threaded aperture 3 is screwed an exteriorly threaded nipple 6 forming part of -the body 7 of a fourway cock. The body 7 is made with a valve chamber 8 within which a rotatable valve plug 9 is held by means of'a pair of nuts l0 mounted upon the threaded stem 11 of said valve 9, a washer 12 being -positioned between said nuts and the body 7 ofA the cock, as usual. At its opposite larger end the valve plug 9 is made with an integral handle 13 by means of which. it is manually operated, said handle being formed at one end with a pointer 14 c'o-operatingwith the position indicating lettering Soap, Stop and Water cast upon the outer face of the body 7. Stops 15 and 16 in the form of lugs on said outer face engage the handleV 13 to limit the movement thereof to one-half of'a revolution.

The cock body 7 is made with radially disposednipples 17 and 18 projecting from opposite sides thereof, the nipple 17 being made with a main inlet port 19 through it, which communicates with the valve chamber 8, and the nipple 18 being made with a' main outlet port 20 through it, which also ,com municates with said valve chamber. The axes o14 these two ports 19 and 20 are alined, relatively, but offset with relation to the axis of the valve 9 as will be clear by reference to Figs. 6 and 7 where the line is shown passing through the axis of said valve. Formed transversely through the valve 9 is a port 21 which is correspondingly offset relativel to the axis of the valve 9, the vend of said port 21 co-operating with the ports 19 and 20 so that ,when handle 13 occupies one extreme position against stop said ends register fully, each with one of the ports 19, 20, as shown in Fig. 6, and so thatwhen handle 13 occupies its other extreme position against stop 16 said ends register only partially with the ports 19 and 20 thereby restricting the flow from port 19 through port 21 to port 20.

Opening into valve chamber 8 at right angles to the ports 19 and 20 is a pair of upwardly extending by-pass ports 225 and 23 formed in the body 7. Fixed within the uppe'r ends of the ports 22 andA 23, re-

spectively, areV two tubes 24 and 25 whose upper ends occupy positions within a shield 26 having a funnel-shaped sheet metal body 27 and a wire gauze top wall 28. The ends of the ports 22 and 23 which open into the valve chamber 8 are disposed to co-operate, respectively, with the proximate ends of ports 29 and 30 formed as grooves in the periphery of the valve plug 9,'said grooveports being angularly or spirall'y disposed so that their separated ends are adapted to co-operate with the inner ends of the main ports 19 and 20. Thus whenthe valve plug 9 occupiesv its second 'position where the handle 13 is against st0p`16,l Ithe ports 19 and 20 are connected, by ports 29 and 30 with ports 22 and 23 and restricted communication is at the same time established between ports 19 and 20 by the port 21 of the valve plug. It will thus be clear that with the valve plug 9 occupying this position (Fig. 7) water entering inlet port 19 under pressure or head will not only pass directly through the port 21 into outlet port 20 but also upwardly through ports 29 and 22 and tube 24 intothe interior of vessel 1 and then from the latter downwardly through tube 25, and ports 2,3 and 30,' into outlet port 20. This diversion of a portion of the water through the-vessel 1 is occasioned, not only by the pressure or head Within the inlet port 19, but also by the suction or aspiratoreffects produced within outlet port 20 at the discharge end of port 30 by the water discharging from the port 21 of the valve plug at one side only o f the outlet port.

Thenipple 6. of the body of the cock extends through an aperture formed through a bracket r31 and said bracket is clamped rigidly tothe vessel 1 by a ange 32 provided upon said body; a gasket 33 of leather or the like being placed between said bracket and the vessel to close the j oint.

Screw holes 34 in bracket 31 provide for fastening said bracket to a wall or other suport. p The inlet nipple 17 has telescopically applied to it one end of a iiexiblehose pipe 34 that is rigidly fastened thereto by means of a clamp consisting of a metal strap 35 surrounding the portion of the hose occupied by the nipple, and a bolt 36 and nut 37 by meansof which the ends of the strap are drawn together. AThe, ends of the strap are extended beyond the bolt 36 to provide curved Vspring jaws 39. These spring jaws are provided for a purpose presently to be described. y

At the opposite end of the section of hose 34 is a cup-shaped socket 40 provided with a ported nipple 41 litted telescopically within said end and to which the latter is clamped by a strap' 42. Straddling the socket 40 and fulcrumed thereon is a lever 43 to one the other arm of the lever 43. As herein shown the means by which said 4end of thechain is separably and adjustablyronnec'ted with the lever 43 consists of a forked or double-tined hook 48 pivotally connected 'at' 49 to said lever 43, the pivot 49 being the same distance from the fulcrum of lever 43 as the pivotal connection 44 and disposed directly opposite the latter. When a link of the chain 45 is passed into position between the tines of the hook 48 the next lowest link engages said tines so as to lock the chain and hook together.

The outlet nipple 18 of the four-way cock has telescopically applied to it one end of a flexible delivery hose 50 that is fastened in position thereon by means of a clamping strap 51. The opposite end of. the delivery hose 50 is fitted telescopically onto the nipple 52 off a spraying nozzle 53 to which it is clamped by the end convolutions of a coiled helical spring 54. A few convolutions of spring 54 at each end thereof are made to Vtightly clamp onto the flexible hose 50 while the intermediate convolutions which constitute the greater part of the spring are larger 1n diameter than the outside diameter of the hose 50. The spring 5 4 thus .fortable to the hand regardless of the tem` perature of the water passing through the hose, and of the hose itself. This, of course, is desirable when using the apparatus with The socket 40 is provided to support said hose in anA out of the Way Aposition. v

The soap used with my apparatus may be in the form ot' lumps which are placed within the vessel 1, access to the interior of the latter being had by removing the cover 4. Thus when the apparatus is in use with valve 9 occupying the position shown in Fig. 7 the water diverted or by-passed through vessel 1 is brought into contact with the soap which is dissolved and entrained by said water so that the liquid discharged rom port 23 into outlet 20 is a mixture of soap and water.
